5 Claims.

The herein disclosed invention relates to oar locks and has for an object to provide an oar lock which can be attached to the car without using nails, screws or rivets or other means which require drilling or weakening of the oar.

Another object of the invention resides in providing a construction by means of which the position and angularity of the blade of the car with reference to the oar lock may be easily and quick ly adjusted.

A still further object of the invention resides in providing an oar lock which may be easily and quickly applied to the oar.

A feature of the invention resides in providing an attachment for the car including a clamp having jaws formed with arcuate surfaces adapted to closely fit the outer surface of the shaft of the oar.

An object of the invention resides in constructing the clamp with legs extending downwardly from said jaws and spaced from one another and in further providing arms extending upwardly from said jaws and spaced from one another and in further providing a bolt extending through said arms and drawing the parts together to at: tach the attachment to the car.

An object of the invention resides in providing a support for the attachment having spaced flanges between which the legs of the attachment are disposed and in further providing a pintle extending'through holes in said legs and flanges and supporting the attachment for swinging movement about the axis of the pintle.

Another object of the invention resides in pro viding lateral projections on the ends of said pintle and in applying to said pintle sleeves encircling said pintle and extending through the holes in said flanges and engaging the projections on said pintle.

A still furtherobject of the invention resides in constructing the holes in said legs smaller than the diameter of said sleeves so that said legs butt up against said sleeves and urge the sleeves against said projections when the bolt is tightened and thus prevent the legs from being forced against the flanges of the support and causing friction therebetween.

Another object of the invention resides in providing a tubular spacer on said pintle disposed between said legs and fitting loosely therebetween, said spacer preventing said sleeves from becoming disengaged from the bearings in said flanges.

Another object of the invention resides in providing a mounting attached to the gunwale of 2 the boat and having a bearing in which a stud issuing downwardly from the support is pivoted.

An object of the invention resides in providing an oar lock which can be constructed principally from heavy sheet metal or bar stock.

Other objects of the invention reside in the novel combination and arrangement of parts and in the details of construction hereinafter illustrated and/or described.

In the drawings:

Fig. 5 is a fragmentary cross sectional view of the attachment and support taken on line 5-5 of Fig. 1.

Fig. 6' is a view similar to Fig. 5 of a modification of the invention.

In the use of cars in connection with row-boats and similar boats, it has been found that the shaft of the oar is greatly weakened where rivets, screws or nails are secured to the same for attaching the oar lock to the oar or for securing other structures for cooperation therewith. This weakening of the car causes the car to break at such locality when undue pressure is exerted upon the same. The instant invention provides a construction where the oar lock may be attached to the oar without drilling the car or applying nails or screws to the same or without, in any manner, weakening the shaft of the oar at the locality of attachment of the car lock thereto.

The structure shown in the drawings consists of an attachment including a clamp comprising two jaws having curved portions adapted to fit about the shaft of an oar. Issuing upwardly from these jaws are spaced arms through which a bolt extends and by means of which the jaws are urged into engagement with the shaft of the car. Issuing downwardly from said jaws are legs which are received between upstanding flanges formed on a support for the attachment. A pintle passes through holes in the said flanges and 3 legs and pivots the attachment for swinging movement relative to the support. On the ends of the pintle are projections and encircling said pintle are sleeves which pass through the holes in the flanges and engage said projections. The holes in said legs are smaller in diameter than said sleeves and said legs engage said sleeves and urge the same against said projections and thus prevent the legs from being forced against the flanges of the: Support to cause undue friction therebetween; A tubular spacer 'enoircling the pintle and disposed between the legs of the attachment prevents the sleeves from becoming: disengaged from the holes in the flanges. support includes a stud extending in a downward direction and journalled in a bearing formed on a mounting attached to the. gunwale cf the boat.

For the purpose of illustrating the application? of the invention a portion of a boat III has been shown. which. includes. a. gunwale.

This clamp comprisestWo, clamp members 38 and- 33 which are. preferably constructed of. sheet. metal or bar stock and which are substantially the same in construction. The clamp member 38 has an arcuate jaw adapted to fit about a portion of the outer surface of the shaft I! of the car I6. The clamp member 39 is similarly constructed with a jaw M which likewise fits about a portion 'of the shaft I! of oar I6 and which is disposed opposite the jaw 40. The jaws 40 and 4| have depending therefrom legs 42 and 43 which are spaced froinone: another and which; are constructed with registeringholes- 44 and 45. The upper portions of the jaws 40 and 4| have issuing upwardly therefrom arms 46 and 41 Which are spaced from one another and which are constructed with registering holes 48 and 49. The hole 48 is. constructed square to receive the squared portion 50 of the head 5| of a carriage bo1t'52. The hole 49 may be circular or squared if; desired to receive the shank 53 of said bolt.

Bolt.52 is next applied .and. thenutiktightened down. to. cause. the.- clamp members to. securelyclamp the car and attach the attachment thereto.

The ;use of theinvention;is..obvious. Theoars are attachedas explained. If. the ang ularitywf the blade of the oar-is net-pro er or'the distance apart of the'handles of the car is not suitable,

the nuts 54-can be'loosened and-the oars readjusted. Where a boat sometimes has a crooked keel or is otherwise not symmetrically constructed, the boat will have a normal tendency to pull to one side. This can be overcome by my-invention extremely. economical cost. 'By means of the construction shown, injury to the car in the attachment of the car look thereto is entirely prevented.

At' the same time the oar can be readily adjusted for' position andangularity with respect to the boat so as to procure the best service from the cars. The attachment of the car look is at all times secure so that the attachment cannot be lost or easily displaced on the car.

In Fig. 6 a modification of the invention has been shown. In this modification the support and attachment 2| are the same as shown in Fig. 5 and the description thereof will not be repeated. The same reference numerals will be used to indicate the corresponding parts. In this form of the invention a bolt 65 is used instead of the pintle 51 which bolt has a head 66, a threaded shank 61, and a nut 68 screwed thereon. On this bolt is mounted two bushings 69 which are formed with enlarged portions 10 and reduced portions 1| forming shoulders 12 therebetween. These bushings are mounted with the enlarged portions 10 in the holes 55 and 55 in the flanges 3| and 32 and with the reduced portion H in the holes 44 and 45 in the legs 42 and 43. Between the bushings 69 is disposed a sleeve 13 against which the ends of reduced portions 10 of the said bushings abutt. The nut 68 is clamped down tight and the assemblies are free to rotate in the holes and 56. In clamping up bolt 52 the legs 42 and 43 are urged against the shoulders I2 and spreading of the said legs resisted thereby. This form of the invention operates in identically the same manner as that previously described.

Changes in the specific form of the invention,

as herein described, may be made within the scope of what is claimed without departing from the spirit of the invention.
